ASTM A500 ndi ASTM A501onsewo amayang'ana zofunikira zokhudzana ndi kupanga chitoliro chachitsulo cha carbon steel.
Ngakhale pali zofanana muzinthu zina, zimakhalanso ndi mawonekedwe awoawo ndi ntchito zawo.
Kenako tiwona kusiyana kwakukulu pakati pa ASTM A500 ndi ASTM A501 ndi momwe amagwiritsidwira ntchito pazinthu zosiyanasiyana.
Njira Zopangira
Njira Zopangira ASTM A500
Chitoliro cha ASTM A50 chidzapangidwa ndi njira zopanda msoko kapena zowotcherera.
Machubu opangidwa ndi welded amapangidwa kuchokera ku chitsulo chopindika chathyathyathya pogwiritsa ntchito njira ya electric-resistance-welding (RW).
Njira Zopangira ASTM A501
Mipope iyenera kupangidwa ndi imodzi mwa njira zotsatirazi: osasunthika, kuwotcherera ng'anjo yamoto (kuwotcherera mosalekeza);kuwotcherera kukana kapena kuwotcherera kwa arc pansi pamadzi.
Idzatenthedwanso pamtanda wonse ndikusinthidwa ndi kuchepetsa kapena kupanga njira, kapena zonse ziwiri.
Mapangidwe omaliza a mawonekedwe adzapangidwa ndi njira yotentha yopangira.
Njira Zosiyanasiyana Zopangira
Miyezo yonseyi imalola kugwiritsa ntchito njira zopangira zitoliro zopanda msoko;
Ngati njira yowotcherera ikugwiritsidwa ntchito popanga, ASTM A500 imagwiritsa ntchito electric-resistance-welded (RW), pamene ASTM A501 imalola njira zosiyanasiyana zowotcherera, kuphatikizapo electric-resistance-welded (RW), kuwotcherera arc pansi pamadzi (SAW), ndi zina zotero.
Komabe, ASTM A501 imafuna kuti chitolirocho chizitenthedwa, chomwe chimathandizira kukonza mawonekedwe ndi makina azinthuzo.Cholinga cha thermoforming ndi kukonza zinthu zakuthupi ndi kutentha kuchiza chitoliro chisanathe mawonekedwe ake.
ASTM A500 ilibe zofunikira zotere.
Gulu la Maphunziro
Kugwiritsa Ntchito Size Range
Chemical Components
Kuphatikizidwa palimodzi, pali kusiyana kwina pamapangidwe amagetsi a carbon steel structural chubu zomwe zafotokozedwa mumiyezo iwiriyi, ASTM A500 ndi ASTM A501.
Mu ASTM A500, Gulu B ndi Gulu D ali ndi zofunikira zofanana za mankhwala, pamene Gulu C ili ndi mpweya wochepa wokhudzana ndi B ndi D. Mu ASTM A501, mankhwala a Gulu A ndi ofanana ndi a Gulu B, pamene Gulu C ili ndi mpweya wocheperako poyerekeza ndi Gulu B.
Mu ASTM A501, mankhwala a Gulu A ndi ofanana ndi a Grade B ndi D a A500, koma m'kalasi B ndi C mpweya wa carbon umachepa, manganese amawonjezeka pang'ono, ndipo phosphorous ndi sulfure zimakhala zochepa kuposa mu Grade A.
Zomwe zili mkuwa zimakhalabe zofunikira zosasinthika pamakalasi onse.
Zofunikira zosiyanasiyana za kapangidwe ka mankhwala zimawonetsa zofunikira zenizeni zamiyezo iwiriyi pakupanga ndi kugwiritsa ntchito kosiyanasiyana, kuwonetsetsa kuti zinthuzo zikukwaniritsa zofunikira zaumisiri ndi kapangidwe kazinthu zosiyanasiyana.
Mechanical Magwiridwe
ASTM A500 Mechanical Performance
ASTM A501 Mechanical Performance
Ma Mechanical Properties Osiyanasiyana
Zipangizo mu A501 nthawi zambiri zimapereka mphamvu zambiri chifukwa cha kuwonjezereka kwa chitsulo kuchokera pakupanga kotentha.
Ntchito Zoyeserera
Zofunikira zosiyanasiyana za zinthu zoyesera mumiyezo iwiriyi zikuwonetsa njira zopangira ndi zomwe amapangira machubu awiri osiyanawa.
Muyezo wa ASTM A500 umafunika Kusanthula kwa Matenthedwe, Kusanthula Kwazinthu, ndi Katundu Wamakina kuwonjezera pa Mayeso a Flattening, Flaring Test, ndi Wedge Crush Tes kuwonetsetsa kuti kuzizira kwapangidwe sikukhudza zinthu zakuthupi.
Muyezo wa ASTM A501 umatsindika ndondomeko ya thermoforming, ndipo popeza mankhwala opangidwa ndi thermoform amatenthedwa kale panthawi yopanga, mayeserowa akhoza kuonedwa kuti ndi osafunika chifukwa kutentha kwa kutentha kwatsimikizira kale pulasitiki ndi kulimba kwa zinthuzo.
Madera a Applicatio
Ngakhale kuti zonsezi zimagwira ntchito yomanga, kutsindika kudzakhala kosiyana.
Machubu a ASTM A500 amagwiritsidwa ntchito kwambiri pomanga nyumba, kupanga makina, mafelemu agalimoto, ndi zida zaulimi chifukwa chakuzizira kwake kopinda komanso kuwotcherera.
Machubu a ASTM A501 ndioyeneranso kumanga ndi zomangamanga zomwe zimafunikira mphamvu komanso kulimba mtima, monga kumanga mlatho ndi zida zazikulu zothandizira, chifukwa chakulimba kwake komanso mphamvu zake.
Miyezo yonseyi imapereka chitsogozo chopangira machubu apamwamba kwambiri a carbon steel, koma kusankha bwino kumatengera zofunikira ndi zopinga za polojekiti inayake.
Ngati kapangidwe kake kakufunika kuchita bwino m'malo otentha kwambiri, ASTM A501 ikhoza kukondedwa chifukwa kulimba kowonjezereka kuchokera kukupanga kotentha kumapereka kukana kwabwinoko pakusweka kwa brittle.Mosiyana ndi zimenezi, ngati nyumbayo iyenera kumangidwa kuti ikhale ndi malo amkati, ndiye kuti ASTM A500 ikhoza kukhala yokwanira, chifukwa ikhoza kupereka mphamvu ndi ntchito yofunikira, pamene ingakhale yotsika mtengo.
